TC9401 - Microchip Technology

TC9401 Voltage-to-Frequency/Frequency-to-Voltage Converters

The TC9400/TC9401/TC9402 are low cost voltage-tofrequency (V/F) converters, utilizing low power CMOS technology. The converters accept a variable analog input signal and generate an output pulse train, whose frequency is linearly proportional to the input voltage. The devices can also be used as highly accurate frequency-to-voltage (F/V) converters, acceptin.
